Right. You need to keep track of that yourself, like with a Peer class that can hold onto those streams and act as their delegate. NSNetService doesn't really have anything to do with those streams.

I recommend you ask this question in the hated-by-some developer forums (forums.developer.apple.com). Quinn the Eskimo fields questions there most days, and he’s exactly the person to give you the

Hi all, I’m trying to add a peer-to-peer communication feature to a game I’m developing. So far it’s half working, which given the paucity of documentation, I’m actually quite proud

It wouldn’t be a valid filesystem if it didn’t support the system calls like stat() that NSFileManager uses to get file attributes. Now, not every filesystem supports every attribute (you’re not

Breaking stuff isn’t always a red line for Apple, but from your reaction I’ll take it that there’d have been an righteous outcry by now were it the case. I’ve had my head stuck in the sand as

If it did, it would break most apps, so no. —Jens

Apologies if this is a dumb question, but I'm wondering whether we'll still be able to call NSFileManager api's like attributesOfItem and get back things like NSFileReferenceCount and the like. Does

Jens; Thank you for the opportunity to expound on this. See below… A look at the discussion for NSFileHandle’s writeData: method provides the following: "This method raises an exception if the

It does seem absurd that the most fundamental APIs — the C standard library and POSIX/Darwin system calls — aren’t supported by Xcode’s documentation features. Especially since the header

I’ve been happy with Acorn for those purposes for years. The documentation is great too. https://flyingmeat.com Jim Crate

Try canva.com. They have a reasonable free account for graphics editing online, apparently they have an iOS app too, although I've never tried that. Sandor

Um... I might just write code to do that. The 'hardest' thing is probably to get text positioning right. For general image manipulation I use Pixelmator. I like it but I wouldn't exactly call it

How about Gimp?

Hi, Can anyone recommend a light weight Image Creation and Editing App for the Mac? I’d like to be able to create images with fixed dimensions and background colour and be able to resize

Hi all, At the moment I am saving tiff files in a one-liner using [[myNSImage TIFFRepresentation] writeToFile:atomically:]. I am considering a change to write rather large multi-page tiff files

Look at fcntl() (man fcntl). It has an operation parameter of F_SETNOSIGPIPE and F_GETNOSIGPIPE to manage the SIGPIPE signal handling on a file descriptor. Won’t find it in the Xcode

A broken pipe usually means that one end of the connection has been closed for one reason or another. You don’t show the actual read and write code, but that is most likely where the problem occurs.

Well, this is so far a blind alley. I can’t find any mention of functions called signal() or ioctl() in the current (Xcode 8) documentation browser. But then, it seems we’ve lost the ability to

OK, makes (some) sense, thanks. I’m wondering why the file descriptor would be ‘closed at the other end’ though - does that mean one of us (the command line tool is not my code but I am
